About This Product: Kink Pillar 2-Piece BMX Crankset

The Kink Pillar 2-Piece BMX Crankset at J&R Bicycles features innovative design that uses a one-piece forged backplate linking the pedal and spindle bosses. This also acts as a durable foundation for each crank arm and fortifies weak spots found in traditional tubular cranks. The hollow chromoly spindle is TruTherm heat treated post-weld for even more strength. Right-hand or left-hand drive compatible, also compatible with regular and Micro drive sprocket bolt bosses.
